Periodic Reporting for period 2 - IMMQUIRE (INTEGRATED MECHANICS FOR MODULAR QUANTUM RECONFIGURABLE CIRCUITS)

Periodo di rendicontazione: 2023-04-12 al 2024-04-11

Sintesi del contesto e degli obiettivi generali del progetto

The aim of IMMQUIRE is to overcome the scaling limitations of quantum technologies by developing a modular on-chip platform equipped with mechanical reconfiguration to optically interconnect and control spin qubits. This system has the potential to generate qubit entanglement on an unprecedented scale and accelerate the development of quantum computers, cryptography, and a quantum internet.
Specific objectives are a) developing a mechanically reconfigurable PIC platform designed to b) strain-tune transferred diamond spin defects into spectral alignment, and c) reconfigure PICs for spin interaction and quantum logic.

At the conclusion of the project, we have shown large-scale integrated photonics and electronics for spin-optic based quantum information processing. This includes the demonstration of scalable waveguide- and cavity-coupled silicon color centers/spin defects, the integration of superconducting single-photon detectors, and diamond color center quantum systems on chip with more than 1000 qubits. These bring forward to generating large entangled states on chip for quantum computation and communication.

Lavoro eseguito dall’inizio del progetto fino alla fine del periodo coperto dalla relazione e principali risultati finora ottenuti

We have demonstrated integration approaches for spin-photon interfaces into photonic integrated circuits and microelectronic chips. This includes a system integrating record-high (1024) number of controllable spin-optic interfaces, and spin control of a diamond color center on a nanophotonic chip. We have also developed a method to integrate superconducting single-photon detectors onto arbitrary photonic platforms, including mechanically-reconfigurable platforms.
We also started investigating a new type of color center in silicon with telecommunication wavelength operation, and demonstrated waveguide and cavity integration. Using the new silicon color centers, we demonstrated optical tuning of their operation wavelength.

Progressi oltre lo stato dell’arte e potenziale impatto previsto (incluso l’impatto socioeconomico e le implicazioni sociali più ampie del progetto fino ad ora)

We have developed large-scale integrated photonics and electronics for spin-optic based quantum information processing. In addition, we have demonstrated the first waveguide- and cavity-coupled silicon color centers and their spectral tunability, key for quantum information processing. To complete the system, we demonstrated the integration of superconducting single-photon detectors into arbitrary photonic substrates, enabling processing-free high-quality detectors for quantum applications. These demonstrations brings us a step forward to generating qubit entanglement on a large scale for quantum computation and communication.
